PATENT OFFICE.

' r WINDOW.

To all whom it may concern:

Be 1t known that I, WILLIAM JOHN SUM- MERBELL, a citizen of thev United States, andV a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Window, of which the followlnglls a full,.clear, and exact description.

his invention is an improvement in fireproof wlndow vframes and sash frames, having Of reproof material, preferably hard asbestos board, and a further intermediate `layer of reinforcing, ordinarily sheet metal,

the Whole being securedftogether by bolts With the nuts located on the Inside, whereby` it will not bepossible to unbolt the frameat the outside ofthe building and in this manner enterthe window.

The invention further resides in certain .other novel features of the frame construct1o n hereinafter p `rticularly pointed out in the annexed claims.

described and Reference is tobe-had tothe accompany- Ing drawings forming@ part of this specification, in whichsimilarcliaracters of reference indicate corresponding g arts in all the views.

Figure lis a front eevation of a Window'- embodying my improvements; Fig. `2 is a vertical'section of the same illustrating in dotted outline the manner in which the upper sash opens; Fig. 3 is. through ,the window frame and sash frames Onan enlarged scale; Fig. 4 is a cross-section through the window frame and the upper sash frame just above the latters point of pivotal support Fig., 5 is a corres ending view of the wlndow frame and the ame of the lower sash; Fig. 6 is aface viewof the section throu h.

' upper sash reinforcing for the sash frames, showing the transverse muntin in 'dottedoutline as when the reinforcing is used for a sash constructed in accordance With the bfittom sash shown `in Fig.A 1;. Fi 7 is a cross-section through oiie of the sas muntins; and Fig. 8 is across the window-frame and the ame Just below the latters pomt of pivotal support.

Mo e specifically described, a Window fram or 'a sashframe constructed in 'accordance with my inventonjs composed of a' a vertical 'section' LPatented Oct-'13, T908.

plurality of la ers of material, an outerlayer 10 forming t e outer facing, composed of such jfireproof material yas hard .asbestos board, and an inner layer 11 formin theinner facing, ofthe same material. T esefacings or layers are separated by an intermediate layer 12'of` like material, and a reinforcing member 13l of sheetmet'al. case of the sash frames this reinforcing is made in a single piece, as illustrated in Fig.` 6. The window frame as "shown in-Figs. 3,' 4 and -5, in addition'to the intermediate layer 12, is provided with anvadjacentllayer 12, equal in thickness to the outer-layerl() ofthe sash, which makes the-combined thickness .of the layers 11, 12 and 12a, and thereinforcin equal'to the total thickness of the sas frames, leaving the outerlayer 1-0 of the .window frame to project beyond the sashframes and thereby give the window a neat nish. The several layers of the window frame and the sash frame are respectively secured together by bolts 14, which preferablyhave lain conical heads countersunk in the outer acing and corresplonding slotted nuts 15 likewise let into t e inner facing, this .ari rangement of the bolts obviouslypreventing the frames from be` disassembledfrom-the outside and the building and thewindow entered in this manner. l Before the inner facings of -the frames -ane applied, a nut 16 is threaded on the'bolts I14: y

considerable strain in binding the severalI layers of material together, and also. holds the parts ofthe sash-frame together with the inner facing removed While the sash are being glazed.- Suitable recesses are c t the inner faces of the inner layers of the frame',l

for receiving the nuts lo and permittingof the said la ers seating fiat-against the remforcing andY intermediate layer;

As will be observed from Fig. 3, the frame of the lower sash isimmovable Within the .Window-frame, and is formed at the sides as a part thereof. The upper sash is pivotally supported at opposite sides intermedlate lts length within t e Window frame, so that 1t 1s adapted to swing within the opening, as illustrated in dotted outline in Fig. v2. In order that this sash may form a ood Weather joint with the window-frame wren closed and be brought to a sto when swung to closed position, I preferab y cut away the inner la er orlfacing of the Wlndow frame above the e I v tions of the Below the line of pivotal sup ort of the u Y as indicated at 17a in Fi of pivotal support of the upper sash, as

shown in Figs. 3 'and 4, and extend the ad- .jacent inner facing of this sash, as indicated at 17', to ll u these cut-out or rabbeted porame when the sash'is closed.

per sash I cut away or rab et at' the si e edges its inner facing and correspondingly extend the inper facing ofthe window-frame,

8. The outer facing of the lower rail'of t e upper sashis also extended and beveled on its mner face, as m dicated at 18, and fits against a counterpart beveled portion of the top rail of the u dper ers sash.v In this manner abutting shou I are provided between the window-frame and upper sash-frame above the latters line of pivotal suipo'rt, and corresponding shoulders are provi ed below this line between the up- 20, per` and lower sash-frame and between t e upper sash-frame and window-frame.

v t will be 'observed from Fig. 3 that the outer facing ofthe window frame at the top is extended slightly below `the intermediate layers 12 and 12, so that the parting line between this portion lof the. window-frame and the u per sash-frame is obscured at the outside W en the sash is closed.

Having thus described my invention, I

claim as new and desire to secure by Lettersy Patent:

' 1. A frame constructed of anfouter facing of ireproof material', an intermediate layer of the vsame material, a reinforcing of sheet A35 metal arranged between one of said facings and theintermediate layer, and bolts passin through the facm s, intermediate layer an 2. In a window, a window frame, an upper and lower sash framein the window frame, all of said frames being constructed of a plurality of layers of material, with the layer forming one face of the to'p rail of the lower sash cut out at'the ed e, thelayer forming one face of the window ame being cut out at the edges for a portion of the depth of the uper sash frame and the layer of material orming the opposite face of the window frame bein cut out at the edges for the remainder o the depth of the upper sash frame, and the corresponding layers of material of the up er sash being extended to fill the cut-out e ges of the window frame and the cut-out edge of the top rail of the lower sash frame.

3. In a window, an upper and lower sash, the frames' of which are constructed of a plurality of layers of material, the outer layer of the top rail of the lower sash being beveled off, and the outer layer of the bottom rail of the upper sash being extended below the innerlayer and beveled on its inner face to fit the beveled layer of the top rail of the lower sash. t. l

4. Aframe comprising an outer facing, an inner facing, a reinforcinglbe'tween said facings, and bolts assing t roug'h the facings and reinforcing having nuts threaded thereon, one of which bears directly on the reinforcing and the other bearing on the mner facing. l

'In testimony whereofI have signed my name to this specification in the presence lof two subscribing witnesses. s
